Rotatable guide-roller for flexible tubes and wires



FIG. 1 is a side view of a rotatable guide-roller for flexible tubes and wires showing my new design, the guide-roller having circular symmetry about it's longitudinal axis, such that any side view would be essentially the same as FIG. 1;

FIG. 2 is a top view of FIG. 1; and,

FIG. 3 is a bottom view of FIG. 1. 

The ornamental design for a rotatable guide-roller for flexible tubes and wires, as shown and described.
